在 Ubuntu 14.04 上使用 RVM 安装 Ruby 2.2.2 时出错

Question

这是什么。我第一次做：

rvm get stable
rvm install ruby-2.2.2

没有交易。它向我展示了以下内容：

$ rvm install ruby-2.2.2
Searching for binary rubies, this might take some time.

There was an error(6).

No fallback URL could be found, try increasing timeout with:

    echo "export rvm_max_time_flag=20" >> ~/.rvmrc

There has been an error fetching the ruby interpreter. Halting the installation.

我按照说明增加了超时时间：

echo "export rvm_max_time_flag=20" >> ~/.rvmrc

但没有成交。我也做了 rvm get head 并用更高的超时重新做了一遍，但仍然不好。

如何在 ubuntu 上正确安装 ruby-2.2.2？

Answer 1

我感觉很差劲，但问题是我的 VM 的互联网连接失败了。（我想我错过了 Troubleshooting-101，呵呵）

我更改了 PC 的网络，但 Virtual Box VM 没有更新或连接到新网络。为了增加这个问题，none 命令（ rvm get stable; rvm get head; rvm install ruby-2.2.2 ）发出了警告，所以我导致认为这是别的东西。
